SPECIFICATION forming part of Letters Patent No. 729,418, dated May 26,1903.

Application filed .Tune 30, 1902. Serial No. 113.815. (No model.)

To all whom it may concern.:

Be it known that I, JAMES ROBERTSON, diesinker, a subject of the King ofGreat Britain and Ireland, and a resident of Glasgow,.Soot land, haveinvented new and useful improved devices applicable for takingup shockin the handle-bars of cycles and motor-vehicles and tohand-barrowhandles,hammer-handles,and the like, (for which anapplication for a patent has been filed in Great Britain, No. 25,832,dated the 18th of December, 1901,) of which the following is aspecication.

The object of my invention is to provide handle-bars of cycles, dac.,with such means for taking up shock as will be comfortable to and notliable to injure the users hands.

The improvement consistsl in fitting over the ends of the handle-bar orhandle aspiral or helical spring formed of a metal ribbon or strip of `aconcave-convex cross-section, withvthe convex face outward, and insecuring the end coils of the grip by fastenings to the bar orhandle,while the intermediate coilsare out of contact with the internalbar.

In the accompanying drawings, Figure 1 illustrates the application of myinvention to the handle-bar of a cycle. Fig. 2 is a longitudinal sectioncorresponding to Fig. 1.

Fig. 3 is a sectional view, to an enlarged scale,

the devices shown in Fig. 3, and Fig. 6 is anv end view of thesecuring-cap.

The vspring-strips 1 are coiled spirally, and

y the central coils are larger in diameter than those toward both ends,so that these central coils shall be out o f contact with the centralbar 2 when the coiled grip is applied to the latter. Each coil may bemade in one piece or in several sectional spiral lengths suitably thehandle-bar 2, are held together by a rubber band 8 and inserted withinthe handle.

The wedge 3 has a central opening at its outer Y end and also a slit 2Oacross its face, (see Fig. 4,)

while the part 4 has a cross-head 6 extending up into the hollow underside of the part 3. A retaining-cap? is placed on the whole and has acentral opening, Fig. 6. The end 12 of the grip is bent into theposition shown by dotted lines in Fig. 4, passing through a side opening11 in the cap, Fig. 6, and lying within the slit20 of the part 3. Uponinserting the screw 9 and rotatingit the two wedge-pieces 3 and 4 willbennoved so as to grasp the inside of the bar strongly by expansion. At

' the same time the grip will be prevented from moving by itsdownturnedend 12 lying within the slit 11. If desired, the other end ofthe wire of the grip may be fastened to the bar, as shown at 10, Fig. 1,by a screw; but in allV cases the intermediate coils of the grip are outof contact with the bar 2.

Y "I claim as my invention- 1. A handle for bicycles and the like,consisting of a bar having wound spirally around it a spring-strip ofconcavo-convex cross-section, With the convex face outward, the ends ofthe spiral spring being secured to the bar,

-but the intermediate coils being out of con,-

tact with the bar, substantially as described.

2. A spring-rip for a hollow handle, comprising a spiral spring-strip ofconcave-convexvsection with the convex face/outward, a wedge devicewithin the hollow handle, and a cap having a slot, and the wedge devicehaving a slit in its outer face, substantially'as described.l 4 i Intestimony whereof I have signed my name to this specification in thepresence of two subscribing'witnesses.

JAMES ROBERTSON.
